Ignition Control Module: Testing and Inspection

1. Verify that ECU inputs and outputs are correct.
2. Check the condition of the connector, distributor, ignition coil, and high-tension leads.
3. If all are normal but misfire still occurs, replace the distributor.

NOTE: The igniter is an integral component of the distributor and is not serviced separately.
